+#REGTEST_TYPE=devel
+
+# This reg-test checks the behaviour of the 'curves' and 'ecdhe' options on a
+# bind line.  Its main point is to ensure that the default curve used in
+# HAProxy is indeed prime256v1 (or P-256 depending on the curve's
+# representation). In order to check this, is uses two ssl frontends that have
+# different lists of accepted curves, one of them accepting this default curve
+# while the other one does not. A backend tries to connect to those two
+# frontends by using the default curve, and it should succeed in one case and
+# fail in the other.
+# For some strange reason, OpenSSL 1.0.2 does not behave the same way as later
+# versions when it comes to ECDH and curves related matters. Instead of trying
+# to make it work the same way as the other (more used) versions, we will
+# ignore it and disable this test on OpenSSL 1.0.2.
+# For the same reason, this test is disabled for other SSL libraries as well.
